스토리지 클래스 메모리(Storage Class Memory; SCM)는 비휘발성 속성과 바이트 단위의 임의접근이 가능한 속성을 동시에 보유하고 있는 차세대 메모리 기술이다. 지금까지 많은 SCM 관련 연구들은 SCM 활용 측면에서 성능 신뢰성 고집적도 그리고 에너지 절감 중심으로 이루어져왔다. 이와는 다르게 본 연구는 하이브리드 SCM-DRAM 메인 메모리에서 어플리케이션의 메인 메모리 할당 즉 SCM과 DRAM의 할당을 최적화하여 성능 신뢰성 집적도 그리고 에너지 절감이 시스템 전체적으로 최적이 될 수 있는 방법 연구이다. 본 논문에서는 최적의 성능을 가질 수 있는 SCM과 DRAM의 할당 방법만을 제시한다.
Debit Card Usage as a Rational Choice: The Moderating Effect of Cash Habit
Dung Phuong Hoang,Thong Huy Vu 중앙대학교 경제연구소 2020 Journal of Economic Development Vol.45 No.1
This research takes a new perspective in explaining the willingness to use debit cards in which the use of debit cards is treated as a rational choice over cash, its alternative means of payment. Upon the adaption of rational choice theory, this study comprehensively identifies the costs and benefits associated with debit card usage and tests the effects of these forces on debit cardholders’ willingness to use the card. Moreover, this study also investigates the influence of cash habit on the willingness to use debit cards. This research employed both the qualitative method with in-depth interview to develop hypotheses and measurement scales and quantitative survey on 376 Vietnamese debit cardholders to test the conceptual model. The findings indicate that the willingness to use debit cards can be significantly encouraged by enhancing perceived benefits and reducing perceived adaptation costs associated with debit card usage. Moreover, although the habit of using cash does not directly affect willingness to use debit cards, it significantly weakens the positive impacts of perceived benefits and strengthens the negative impacts of perceived adaption costs on willingness to use debit cards.

Purpose Rates of women with breast cancer have increased rapidly in recent years in Vietnam, with over 10,000 new patients contracting the disease every year. This study was conducted to identify demographic, reproductive and lifestyle risk factors for breast cancer in Vietnam. Materials and Methods Breast density, demographic, reproductive and lifestyle data of 269 women with breast cancer and 519 age-matched controls were collected in the two largest oncology hospitals in Vietnam (one in the north and one in the south). Baseline differences between cases and controls in all women, premenopausal and postmenopausal women were assessed using chi-squared tests and independent t tests. Conditional logistic regression was used to derive odds ratios (OR) for factors that had statistically significant associations with breast cancer. Results Vietnamese women with breast cancer were significantly more likely to have a breast density > 75% (OR, 1.7), be younger than 14 years at first menstrual period (OR, 2.2), be postmenopausal (OR, 2.0), have less than three pregnancies (OR, 2.1), and have less than two babies (OR, 1.7). High breast density (OR, 1.6), early age at first menstrual period (OR, 2.6), low number of pregnancies (OR, 2.3), hormone use (OR, 1.8), and no physical activities (OR, 2.2) were significantly associated with breast cancer among premenopausal women, while breast density (OR, 2.0), age at first menstrual period (OR, 1.8), number of pregnancies (OR, 2.3), and number of live births (OR, 2.4) were the risk factors for postmenopausal women. Conclusion Breast density, age at first menarche, menopause status, number of pregnancies, number of babies born, hormone use and physical activities were significantly associated with breast cancer in Vietnamese women.
